A large piece of iron was reacted with an acid. What would happen to the rate of the reaction had the large piece been finely divided into smaller pieces? (1 point)
It will decrease because the reactant particles are moved farther apart.
It will increase because the reactant particles are brought closer together.
It will decrease because larger particles provide more surface area to react.
It will increase because smaller particles provide more surface area to react.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
